Application filed March 2, 1912. Serial No. G81-.031.

United States, residing at Tamaqua, in the county of Schuylkill andState of Pennsylvania. have invented new and useful Improvenients in Film-i/Vinding lVIechanism` for Moving-Picture Machines, of which the.following isa specification. Q This invention relates to film windingmechanism and particularly to an improvement over the device shown 1nour Patent No. 1,021,617 of MarchQG, 1912.

An object of the invention is to provide means for simultaneouslyrevolving the magazine tray and the winding reel so as to exert an evenpull on the film with the resultantelimination of the snap of the filmas it leaves the magazine tray.

Another object of the invention is to provide a winding reel ofseparable sections whereby the sections can be readily disconnected fromeach other and the wound film left remaining upon one of the sections sothat thisv section can be placed in the tray of the magazine.

Another object of the invention is to construct one of the sections ofthe' separable reel so as to insure the free unwinding or the passage ofthe film therefrom.

Another object of the invention is to provide means for holding the coilor film operatively associated in the tray of the magazine.

Fig. 5 is asection on line 5-.-5 of Fig. 2 showing parts in full lines. Fig. 6 is aside view of one of the Vsections of the windingreel. Fig. is a viewsimilar to Fig. 6 showing a portion of the other section of the vwindingreel. Fig. .8 is a sec- -tion through the central portion of the windingreel. Fig. 9 is aperspective view of the belt tensioning device. A

The moving picture machine A conventionally shown herein may be of anysuitable well known type or construction7 being mounted upon the usualtable B and arranged in proper proximity with the lamp house C. Thetable B is preferably supported by telescopic legs D whereby the tablecan be adjusted angularly with relation to the picture screen so as toinsure the proper framing of the pictures thereon.

lThe upper magazine 1 is disposed upper most with relation to themachine A and secured as at 2 to the front of the said ma- -'chine A isa leaf 3 of a suitable hinge.

through which clamping bolts 6 of the magazine 1 extend. These bolts areprovided with nuts 7 which are adapted to bear against the bottom of theleaf 4 so as to hold 'the same securely frictionally engaged against thebottom of the magazine and hence held in an adjusted position thereon.The hinge embodying the companion leaves 3 and 4 provides means wherebythe upper magazine 1 can be adjusted angularly as to the adjustment ofthe table B whereby the pan ofthe upper magazine is maintained in ahorizontal position.

The magazine l is constructed of metal and it is provided with a.l maincylindrical body portion S and a communicating vertical portion S, thelatter being subs-tan` tially of rectangular configuration in transversesection as clearly shown in Fig. Q of the drawings. One side of each ofthe portions 8 and 8 of the magazine is open7 and as illustrated themagazine carries a suit able closure 9 which is designed to vclose theopenings in the portions 8 and 8 as shown in Fig. 2. The end wall of theporV one of the side Walls et the portion. 8 ot the said magasineextends a lined spindle. 11 upon which a picture reel maybe sup; portedon the initial. showing or display or' the picture, the said spindljebeing adapted to support the reel in the'usual vertical position. il.pan l2 is secured upon a ver tical driven shalt 13 which extends throughthe bottom of the portion 8 et' the said magazine l.. This pan has itsdriyen shaft 1.53 mounted in a suitable bearing' lll upon the bottom ofthe portion 8 and beneath the said bearing and keyed or otherwisesuitably secured to the shaft 13 is a horizontally disposed relativelylarge pulley il. horizontal shaft 16 is mounted as at l? upon the bottomoi the portion 8 and as illustrated it has mounted thereon .suitableidlepulleys 18 Whose peripheral belt grooves 19 are operatively associatedwith the peripheral belt groove Q0 in the pulley l5 so as to insure theproper association ot the driving belt with the pulley 15. 4

The lower magazine 2l which is secured beneath the table supports theusuel driven spindle which has mounted thereon a, pulley 23 whichconforms with the pulley l5 upon the magazine l. A bracket- 1s securedto one side of the lower magazine 2l and extending from Said bracket arestud bolts 25, 'lhese bolts pass through the elongated slot 26 in an arm2? of the belt tightener 28. Clamping nuts upon the bolts 25 are adaptedto engage against the arm Q7 so as to hold the latter in an adjustedposition. The arm 2T is provided with ,oppositelj7 extending portions 30upon which idle pulleys 31 are mounted. A driving belt. l2 is passedover the pulleyY :23 and. over the pulleys 3l and then over the pulleysl5 and i8 hereinbetore described. The said spindle '22 of the lowermagazine 2l is belted as at 33 with the moving picture machine so thatWhen power is applied to the latter for the purpose of drawing the filmtherethrough the power Will be transmitted. by way of the belt 32 to thecoil or roll supporting tray 1Q of the upper magazine l. ln this mannerthe lm can be drawn from the tray of the 4upper magazine to the Windingreel of the lower magazine 2l Without effecting sudden pulling orjerking of the filmB lt is stated that the upper magazine l isadjustable as to the adjustment of the table B which may be required toeliect a proper framing ot the picture on the screen. In View thereoicthe hinge 3 is provided with an' lear 34 Which has pivoted thereto alink 35.

A. similar ear 36 is secured to the bottom ot the magazine l and it alsopivotally supports a link 37. The link 35 has a slot 38 therein throughwhich aj.,bplt 39 of the link 'extends. A'nut 40 on the bolt may beadjusted to engage against the link so as to hold the latter and thelinlr 37 irriatively held ir'r'zably connecteldf.- lili-om thisconstruct-ion i s eif'ident that-"the magazine 'l is operin any requiredadjusted position and the tray 'l2 maintained in l horizontal position.

The winding; reel ll comprises companion fdisks and d3? the'formerhaving secured thereto a hollow hub lll through which a conical hub l5of the disk i3 is adapted to be extended as shown in 8. The hub lllisprovided with radially disposed headed devices 45 which are adapted tobe extended through the bayonet slots l? in the dislr 4t2. The disks andi3 may be rotated relatively so as to bring the heads the devices lilinto the arcuate reduced logs 48 of thebayonet slots. lfn this mannerthe dislrs l2 and i3 are securely connected together and the reel as aWhole may be placed upon the spindle oit the magazine l, and made torevolve therewith. rl`he openings lS in the companion disks are providedwith short branches i9 Which are adapted to receive the lieys or legs 50ot the spindle 2Q in the 'usual Well known manner.
